The Left of Bang Field Manual
Behavioral analysis is not a matter of intelligence — it's a matter of experience. This is the working reference for the method: read the baseline, catch the anomaly, and act in the time before bang.
Foundations
The core mental models the whole method rests on.
Left of Bang
The core timeline: 'bang' is the critical event. Everything before it is 'left of bang' — the window where observation can still change the outcome.
Read →Baselines & Anomalies
A baseline is what 'normal' looks like for a person or place. An anomaly is a deviation from it. You can't spot the anomaly until you've established the baseline.
Read →The OODA Loop
Observe, Orient, Decide, Act — John Boyd's decision cycle. Whoever moves through it faster shapes the situation.
Read →The Rule of Three
One anomaly is noise. Two is a coincidence. Three is a decision point — when you observe three indicators, you act.
Read →Clusters & Decision-Making
Single cues lie; clusters tell the truth. And the most common failure left of bang isn't seeing — it's freezing.

The six lenses for reading people and places.
Kinesics
Reading body language — the conscious and unconscious movements that broadcast intention and emotional state.
Read →Biometrics
Involuntary biological responses — the body's automatic reactions to stress and arousal that can't be consciously controlled.
Read →Proxemics
How people use space and distance — and what changes in proximity reveal about relationships and intent.
Read →Geographics
People's relationship to their environment — who moves like they belong, and who doesn't.
Read →Iconography
The symbols people choose to display — and the beliefs, affiliations, and intentions they signal.
Read →Atmospherics
The collective mood of a place — and what it means when that mood suddenly shifts.
Read →Behavioral Cues & Terms
The working vocabulary of an observer.
Anchor Points
Locations where a person feels comfortable and in control — places they gravitate to and return to.
Read →Natural Lines of Drift
The paths people instinctively take through a space — the routes of least resistance.
Read →Habitual Areas
Zones where people naturally congregate and feel comfortable gathering.
Read →Dominant vs. Submissive
A universal kinesic pair: behaviors that claim space and authority vs. behaviors that yield it.
Read →Comfortable vs. Uncomfortable
A universal kinesic pair: the relaxed signals of ease vs. the guarded signals of stress.
